How To Boost FPS In Cyberpunk 2077 for AMD Ryzen CPUs | Hex Editor

Comprehensive AMD CPU optimization guide for Cyberpunk 2077 using HxD hex editor to boost FPS performance

Understanding the AMD CPU Performance Issue

Following Cyberpunk 2077’s initial release, players across various hardware configurations encountered substantial performance challenges that persisted even after multiple official patches. While CD Projekt Red deployed several updates addressing critical issues, many AMD CPU users continued experiencing suboptimal frame rates and system resource utilization problems that impacted gameplay quality.

The core technical problem revolves around inadequate SMT (Simultaneous Multi-Threading) implementation for AMD processors. Unlike Intel’s Hyper-Threading technology which the game properly leverages, Cyberpunk 2077 fails to distribute workload across AMD CPUs’ logical cores efficiently. This limitation becomes visibly apparent when monitoring system performance through Windows Task Manager, where you’ll notice the game predominantly utilizes physical cores while leaving logical cores underutilized, creating an artificial bottleneck.

The gaming community quickly identified this architectural oversight, with Reddit user UnhingedDoork pioneering a community-driven solution that activates proper multi-threading functionality for AMD processors. This clever workaround has demonstrated measurable improvements in both minimum and average framerates while enhancing overall gaming stability across various system configurations.

Step-by-Step Hex Editing Process

This optimization technique involves direct modification of the game’s executable file using hexadecimal editing software. Critical safety note: Always create a complete backup of your original Cyberpunk2077.exe file before proceeding. This procedure carries inherent risks and should only be attempted by users comfortable with system file modifications.

Thanks to detailed community documentation from Redditor chaosxk, the modification process has been streamlined for accessibility. Follow these comprehensive steps precisely:

• Download and install the latest version of HxD Hex Editor from the official developer website
• Navigate to your Cyberpunk 2077 installation directory: For GOG versions: …Cyberpunk 2077binx64 | For Steam installations: …SteamsteamappscommonCyberpunk 2077binx64
• Create a backup copy of Cyberpunk2077.exe and store it in a separate folder for safety
• Launch HxD and open Cyberpunk2077.exe either by dragging the file into the application window or using File > Open from the menu bar
• The interface will display hexadecimal values representing the executable’s binary code (appearing as sequences like 01 FF 0D)
• Activate the search function using CTRL+F, then select “Hex-values” as the search mode in the dialog box
• Enter the search string: 75 30 33 C9 B8 01 00 00 00 0F A2 8B C8 C1 F9 08 (without quotation marks) – this sequence should highlight automatically
• Prepare the replacement string: EB 30 33 C9 B8 01 00 00 00 0F A2 8B C8 C1 F9 08 (without quotation marks)
• Right-click the highlighted hexadecimal values and choose “Paste Insert” from the context menu
• Save the modified file using the save icon or File > Save, ensuring it retains the original filename Cyberpunk2077.exe

Expert Tip: Verify the modification by checking file size changes and creating a system restore point before launching the game.

Performance Results and Optimization Tips

After successfully implementing this modification, users typically observe immediate improvements in system resource allocation. Your CPU and GPU utilization should become more balanced, resulting in higher consistent framerates across different game environments and noticeable reduction in random stuttering during intensive scenes.

Important Compatibility Notice: This optimization exclusively benefits AMD CPU configurations. Intel processor users should avoid this modification as it may introduce instability or performance degradation since Intel’s Hyper-Threading implementation already functions correctly within the game engine.

Advanced Optimization Strategies:

• Monitor performance gains using tools like MSI Afterburner with RivaTuner Statistics Server
• Combine this fix with driver updates and in-game settings adjustments for maximum benefit
• Test stability across different game areas to ensure consistent performance improvements
• Consider creating multiple backup versions when experimenting with different optimization techniques

Common Pitfalls to Avoid:

• Never modify the executable without creating verified backups
• Avoid using this technique on Intel-based systems
• Don’t skip verification steps after making hexadecimal changes
• Ensure you’re using the correct hex values specific to your game version
